<div class="moz-cite-prefix">Well, never mind, I rebooted the target
and the host systems, did a "repo sync" of my chromeos setup, did
a full firmware rebuild (described in the care and feeding doc)
then did a flash of the coreboot firmware, followed by a flash of
the ec firmware and the target system automatically booted
successfully after the ec firmware flash.<br>
<br>
Perhaps it could have been an issue with unsynchronized ec and
coreboot firmware?<br>
<br>
Anyway, I no longer have a flashing issue.<br>

<p>Hi folks, I have, for the first time ever, tried to flash the
EC firmware on a Google Grunt EVT platform. I have succeeded in
the past flashing the coreboot image but the command sequence to
flash the EC is somewhat different. Here is the output I see:</p>
